Abstract

A boron-substituted polysilazane in which the boron is derived from a borane and is bound to the polysilazane through boron-carbon bonds is disclosed. The polysilazane is prepared by reacting a silazane ammonolysis product containing at least one 2-6 carbon alkenyl or alkenyl group with a borane containing at least one B-H group per molecule. The boron-substituted polysilazane can be used to prepare silicon carbide-containing ceramic articles.
